Can Spin Momentum-Dependent Affect Particles' Orbital Motion Alone?It is well-known that light can carry both linear momentum and angular momentum (AM) when interacting with a small particle, the optical linear momentum or/and AM can be transferred to the particle, resulting in observable mechanical effects.
Unlike vor...Jun 28, 2020 -
Researchers Proposed A High Performance Novel Superfluorescent Fiber SourceHigh-power tunable light sources around 1 μm wavelength region is a mature and widely used technology. Such high power, wavelength tunable Yb-doped fiber lasers (YDFLs) light sources are extensively used as excellent pump sources.
However, the stochast...Jun 24, 2020 -
Can Metallic Metasurfaces Used for Terahertz Nanofilm Sensing?For ultrasensitive sensors, the high Q resonance with extremely narrow bandwidth is important and necessary, which indicates the lower rate of energy losses and supports strong interaction between electromagnetic waves and analytes.
However, the metalli...Jun 16, 2020 -
Deep learning networks find a new application on phase-contrast imagingPhase-contrast imaging has been widely applied in optical and X-ray measurements since the phase contains information about the 3D morphology and refractive index of the specimen. A phase map can be retrieved from a single-distance coherent diffraction imag...Jun 10, 2020 -
